This document discusses a methodology for determining toll rates for a six-lane highway project in India. It analyzes factors that affect toll rates such as traffic growth rates, vehicle characteristics, and project costs. Traffic surveys were conducted along the highway corridor from 2013 to 2040 to forecast demand by vehicle type. The estimated total project cost is over Rs. 108 billion to be recovered over a 9855 day concession period, equating to over Rs. 1 billion per day in toll revenues. Based on the traffic projections and cost recovery requirements, the methodology calculates optimal toll rates of Rs. 53 for cars, Rs. 212 for light commercial vehicles, Rs. 132 for trucks and buses, and Rs. 227 for multi-axle vehicles to
